What recent observation has prompted scientists to challenge Tutt's hypothesis about the cause of industrial melanism?Multiple choice question.Reversal of industrial melanism is not correlated with the re-appearance of lichens.Selection against melanism in recent years seems to be correlated to the disappearance of pollution.Selection for melanism in recent years is not correlated with the color of tree trunk

The most commonly accepted hypothesis that explains industrial melanism and the reversal of industrial melanism is that Blank______.Multiple choice question.moths with coloration that matches their background are less susceptible to predation by birdspollution causes the leaves of trees to fold, providing less resting places for the light colored mothspollution tends to kill off light colored trees which are typically used by light colored moths

The reversal of melanism after the introduction of pollution control laws has been observed Blank______.Multiple choice question.in both Europe and North Americaonly in limited areas of the United States (e.g. Detroit)only in Englandonly in Europe

Where has industrial melanism been observed?Multiple choice question.Throughout Eurasia and North AmericaOn a few large islands (for example Great Britain)In several European countries only

Select all that applyWhich of the following are recent observations that have challenged Tutt's hypothesis about peppered moths?Multiple select question.In some areas, lichens never changed even though dark moths became predominant.In some areas, evidence suggests that moths rest on leaves in the treetops, not trunks.There have never been direct observations of birds preying on the dark peppered moths.Light moths in some areas increased in frequency long before lichens re-appeared.

In 1896, J. W. Tutt proposed that light colored peppered moths were more visible to predators on Blank______.Multiple choice question.sooty trees that have lost their lichens due to pollutionthe trunks of white birch treestrees that have died due to heavy pollution
